Answer:

The scale factor is 4.5

Step-by-step explanation:

Scale factor from ∆RST to ∆XYZ = side length of ∆XYZ / corresponding side length of ∆RST

Thus:

XY corresponds to RS

XY = 45

RS = 10

Therefore:

Scale factor = 45/10 = 4.5

Scale factor from ∆RST to ∆XYZ = 4.5

Are rectangle or garden has a length of 10.25 feet and a width of 6.2 feet. Another rectangle or garden has a length of 20.5 fee
Alinara [238K]
Hello!

The formula for finding area of a rectangle is length × width

<em><u>1st garden
</u></em>l = 10.25
<u><em /></u><em />w = 6.2

6.2 × 10.25 = 63.55

Area = 63.55 ft²

<em><u>2nd garden</u></em>

l = 20.5
w = 12.4

20.5 × 12.4 = 254.2

Area = 254.2 ft²

Divide the bigger area by the smaller area

254.2 ÷ 63.55 = 4

???add up the sides?????
CaHeK987 [17]

Answer:

PR = 20

Step-by-step explanation:

The perimeter is the sum of the 3 sides, thus

4z + z + 3 + 3z + 2 = 45 ← simplify left side

8z + 5 = 45 ( subtract 5 from both sides )

8z = 40 ( divide both sides by 8 )

z = 5

PR = 4z = 4 × 5 = 20
